JAMES JAR-PRINTER, OF NEW HOPE, NEW YORK.

FENGE-POST'DI 'tlVER.

SPECIFICATION forming part of Letters Patent No. 224,578, dated February17, 1880.

Application filed September 23, 1879 i To all whom it may concern Be itknown that I, JAMES CARPENTER, of New Hope, in the county of Cayuga, inthe State of New York, have invented new and useful Improvements inDevices for Driving Fence-Posts, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to an exceedingly sim ple, cohvcnient, andefiicient implement designed for driving iron posts or pipes into theground, and which may be used either as a sledge or in the manner'of a.weighted drop or a pile-driver, and is readily applied to the object tobe driven, easily operated thereon without the. aid of auxiliarymechanical appliances, and readily removed. therefrom without theinconvenience and delay of uncoupling or disjoining the members of theimplement or loaving parts of same on the article driven.

The invention is clearly illustrated in the accompanying drawings,wherein- Figure 1 illustrates the method of applying my improvedimplement to the post designed to be driven. Fig. 2 shows the same inposition for operation. Fig. 3 isan isometric view of the tube or handleand the sledge separated from each other, and Fig. 4 is a longitudinalsection of the'implement applied to the post.

Similar letters of reference indicate corre sponding parts.

A represents the weighted block, in the form of asledge or hammer,provided with a screwtln'eaded socket, 8, extending part way the depthof the sledge, and terminating with a conical or spheroidal cavity, 0,therein, for the purpose hereinafter demonstrated. B denotes the handleof the sledge, consisting of an iron or steel pipe having a threadedend, which is screwed into the socket S of the sledge.

This implement is operated as follows: The post or pipe to be driven isinserted into the handle B, which may be placed with its open endupward, as shown in Fig. 1 of the drawings, or laid on the ground, or inany other desirable and convenient posit-ion. The apparatus thusconnected is then erected and brought into proper position for drivingthe post or pipe 1 in its designated position.

The driving is accomplished by raising and dropping the implemcn t, thedescent being arrested by the collision of the sledge A with the end ofthe post or pipe I, and the force resulting therefrom drives the post orpipe 1? into the ground.

The conical or spheroidal cavity catthe end of the socket S preventsjammingor in nring the end of the post or pipe driven. The handleB,furnishes the means for guiding the ob ject to be driven, and, beingentirely uncon fined in its upward movement, it is readily withdrawnfrom the post or pipe driven. If the same is to be driven deeper thanthe length of the handle B \villadmit in its application, as beforedescribed, theimplemcnt is removed 65 from the object to be driven andused as a sledge for the attainment of the said object.

I do not claim, broadly, the application ot'o weighted drop sliding onthe objectto be driven, as I am aware the same is not now.

What I do claim as my invention, and de sire to secure by Letters.latent, is-* The improved implement for driving iron posts or pipes,consisting of the sledge A, having the tubular handle B, adapted toslide on the object to be driven and unconfined in its upward movement,substantially as described.

In testimony whereof I have hereunto signed my name in the presence oftwo attesting wit-- -nesscs, at Syracuse, in the county of Onon- 8o dagaand State of New York, this 12th day of September, 1879.
